Download full instructions, parts lists, sources with clickable links, construction notes and schematic HERE for PDF version or HERE for MS Word Version.
Both versions have the schematic attached. However, the resolution of the schematic isn't that great. I would recommend saving the image above or downloading it from HERE to ensure you can see everything accurately.

Please be aware that more and more, these devices are becoming illegal, Fox News Story, so its up to you to decide.
Z-Backscatter Van website be aware that these can be installed in many commercial vans. They won't all look like the Mercedes at the website.
There isn't an easy way to shield yourself from x-ray scanning, but you can build an inexpensive detector to notify you of an x-ray source operating in the area.
What you want to build is a simple circuit, such as this one below. Click the image to visit the website.
It uses a photo transistor to detect light and activate a relay which you can wire to an output of your choice.
A photo transistor does NOT detect x-rays, so we'll need to trick it. We will turn x-rays into visible light.
You'll need glue that will dry to a transparent film. You can use spray on or liquid. 3M makes many such products.
You'll also need Zinc Sulfide powder (ZnS). NASCO carries it, and it is widely available.
Zinc Sulfide is the stuff that makes the ghostly green glow in the dark products that activate after being exposed to light. It also glows when exposed to x-rays and gamma rays.
Coat the detector end of the photo transistor with a THIN coat of glue. Dip into the zinc sulfide, let dry, shake off the excess. Repeat one more time.
After it is good and dry use electrical tape or shrink wrap to cover the detector on the photo transistor. Visible light will not penetrate and activate the device if the detector is completely covered. X-rays and gamma rays will and they will cause the ZnS powder to glow, thus activating the photo transistor.
To test your device, bring it near an old tube style television. The older the better, especially if it is black and white. TVs using a Cathode Ray Tube emit x-rays, the older TVs more than the newer ones. You could also use a CRT style computer monitor. VR1 in the circuit adjusts circuit sensitivity, so you may need to adjust it. Ideally, you want it as sensitive as possible.
Or you can go to Granger and buy this.
The NukeAlert keychain is another relatively inexpensive option. It reacts to x-rays and gamma rays as well.
